MACHINERY FOR CRIMPING LEATHER FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 226,876, dated April 27, 1880.

Application filed January 19, 1880.

.To all whom it may concern:

Be it known that I, HENRY O. PEASE, of the city and county of Worcester, of the State of Massachusetts, have invented a new and useful Improvement in Machinery for Urimping Leather forBoots and Shoes; and I do hereby declare the same to be described in the following specification, and represented in'the accompanying drawings, of which Figure l is a front elevation, Figs. 2 and 3 side views, and Fig. 4 a transverse and vertical section, of a machine embodying my invention. Fig. 5 is a top view, and Fig. 6 a longitudinal section, of the compound follower, to be hereinafter described.

Heretofore it has been customary in constructing machinery for crimping the upper of a boot or shoe to have a pair of jaws and a single follower or former to move between them, and with the aid of such jaws to draw and stretch the leather.

In carrying out my invention I use in connection with the jaws a compound follower composed of two exterior followers and an intermediate one-that is, one arranged directly between the said exterior followers, and to move or slide with and independently of them.

In operating the compound follower the leather to be crimped is to be laid upon it, while the intermediate follower is down to its lowest position, between the other two followers, and the said compound follower is below the jaws. Having thus laid the leather upon the compound follower, the latter is to be forced or drawn up between the jaws, so as, with them, to stretch the leather upon it, and after it may have attained a proper altitude its external followers are to be arrested in po sition, and the intermediate follower is to be drawn up between them, so as to still farther raise the leather and slip it between the jaws and the exterior followers, until it may have been drawn out from between the said exterior followers and the jaws.

In the drawings, A represents the frame of the machine, having within it a pair of jaws, B B, suitably supported and provided with adjusting-screws G O G O, by which their distance asunder may be regulated as occasion may require. Between the said two jaws B B is the compound follower, which consists of the two external followers or notched plates, D D, and the intermediate follower or notched plate, E. The two followers D D are parallel to one another and at a distance apart equal to the thickness of the intermediate follower, and said two followers D D are connected at their opposite edges, so as when moved to move each with the other. \Vhen at its lowest position, between and relatively to the external followers, the intermediate follower is supported therein by shoulders at a of it resting upon the tops of the connections I) b of the exterior followers, in which case the upper edge or notch of the intermediate follower is even with those of the exterior followers. The said intermediate follower has applied to it mechanism for moving it in opposite directions between the jaws, such mechanism consisting of belts F F, going around two sets of wheels or pulleys, G G, and fixed at their opposite ends to the said follower, the wheels or pulleys being fixed upon two shafts, c 0, arranged as represented. The upper of the shafts has applied to it a crank, d.

Furthermore, there is to the compound follower mechanism for bolting theintermediate follower to the exterior followers, as occasion may require. In the drawings this mechanism is represented as consisting of two bolts,

6 0, two bent levers, ff, and two springs, h h,

there being one of such springs to each lever, the said levers being pivoted or fulcrumed to one of the exterior followers, and the bolts being hinged to the upper arms of the levers, and passing through the intermediate follower and one or both of the exterior followers. These levers, formed as shown, are operated to move the bolts by being drawn against stationary projections g g, arranged as represented.

Furthermore, the springs are placed between the longer arms of the levers and the compound follower, and serve to move the levers in a manner to cause them to move the bolts into the intermediate follower.

On the compound follower being raised to a position for its exterior followers to remain at rest between the jaws, in order that the intermediate follower may be raised upward still farther, the exterior followers are to be estopped by suitable means or devices, such as shown in the drawings, being projections it from the levers. In approaching its position of rest, as mentioned, the levers f f are carried in contact with the projections g g, and by the latter are moved so as to unbolt the intermediate follower from the exterior followers, which having been accomplished, the intermediate follower next rises, so as to draw the leather upon it up from between the jaws and the outer surfaces of the exterior followers, and thereby stretch it to a greater extent, it being first stretched by being drawn up betweenthe j aws by the exterior followers bolted to the intermediate one.

On subsequently drawing downward the intermediate follower its shoulders a a will be carried in contact with the connections b b, hereinbefore mentioned, and will cause the external followers to descend with the intermediate follower to the necessary position below the jaws for a piece of leather to be crim ped to be applied to the compound follower, the springs h h operating in the meantime or at 1 the proper period to move the levers f f in a manner to cause the bolts to pass into the intermediate follower and lock it to the exterior followers, in order that the three may next rise together up between the jaws.

In a machine for crimping leather or for use therein, I claim as follows:

1. The compound follower, substantially as described, consisting of the intermediate and two exterior followers, arranged and to operate essentially as set forth.

2. The combination of jaws and their supports with the compound follower, consisting of the intermediate and exterior followers arranged with such jaws and provided with mechanism for operating it (the said follower) in manner and with respect to them substantially as specified.

HENRY O. PEASE.
